Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display device used as various thin display panels, and more particularly to a plasma display panel used in such a device to display a color image.

[0002]

2. Description of the Related Art Plasma display panels (PDPs)
Can greatly reduce the depth compared to a CRT direct-view display device or a rear-projection display device, and is a promising means for realizing a wall-mounted large-screen TV.

FIG. 5 is an exploded perspective view showing a conventional example of such a plasma display panel, wherein 1 is a front glass substrate, 2 is a rear glass substrate, 3 is a partition, 4 is an address electrode, 5R, 5G and 5B are R (red), G (green), B respectively
A (blue) phosphor layer, 6 is a display electrode, 7 is a dielectric layer, and 8 is a protective film.

In FIG. 1, a plasma display panel (PDP) includes a front glass substrate 1 and a back glass substrate 2.
Face each other with the partition wall 3 interposed therebetween.

A transparent display electrode 6 composed of X and Y electrodes is formed on the inner surface of the front glass substrate 1, and an address electrode 4 is formed on the inner surface of the rear glass substrate 2 by photo-etching or the like. The display electrodes 6 and the address electrodes 4 are arranged to face each other so as to be orthogonal to each other. The display electrode 6 on the front glass substrate 1 is covered with a dielectric layer 7 having a predetermined thickness formed by printing and firing low-melting glass, and a protective film 8 for gas discharge is formed thereon.

On the back glass substrate 2, partitions 3 are formed for each address electrode 4 by lamination of thick film printing or the like, and adjacent partitions 3 form cells. In these cells, a phosphor layer 5R that emits red light, a phosphor layer 5G that emits green light, and a phosphor layer 5B that emits blue light cover the address electrode 4 in this order. Further, the partition wall 3 is formed up to the wall surface. These phosphor layers 5R, 5R
A dielectric layer may be provided between G, 5B and the address electrode 4. Hereinafter, cells in which the phosphor layers 5R, 5G, and 5B are formed are referred to as R cells, G cells, and B cells, respectively.

[0007] A discharge gas mainly composed of neon is sealed in the space of these cells, so that each cell forms a discharge cell. A cell is located at each intersection of the address electrode 4 and the display electrode 6 which are orthogonal to each other, and each discharge cell forms a pixel. Therefore, a plurality of pixels are arranged in a matrix.

In such a configuration, a voltage is applied between the address electrode 4 and the display electrode 6 which cross each other in the cell to emit light, thereby discharging the discharge gas in the cell and causing a write discharge. Then, two display electrodes 6
By applying a pulse voltage between the X and Y electrodes, the discharge gas is discharged in the cell, and the phosphor layer emits colored light. Therefore, in the R cell, the phosphor layer 5R emits R light, in the G cell, the phosphor layer GR emits G light, and in the B cell, the phosphor layer 5B emits B light, thereby providing color. The image will be displayed.

By the way, according to the PDP having such a structure,
Front glass substrate 1, display electrode 6, dielectric layer 7, protective film 8
Is transparent so that the phosphor layers 5R, 5G, 5B
The color light generated in step (1) is efficiently emitted to the outside through the front glass substrate 1 and the like, and conversely, from this, conversely, the light passes through the front glass substrate 1, the dielectric layer 7, the protective film 8, and the like. External light enters the cell, and the entered external light is reflected by the white phosphor layers 5R, 5G, and 5B in a direction opposite to the incident direction, and emitted from the front glass substrate 1 to the outside. Therefore, when viewed from the front glass substrate 1 side, the entire screen of the PDP looks whitish, and when a color image is displayed on such a screen, the contrast is reduced.

As a method for preventing this, one conventional example is disclosed in JP-A-59-36280. This is shown in correspondence with the PDP having the configuration of FIG.
The configuration is as shown in FIG. In FIG. 6, 9
R, 9G, and 9B are R, G, and B color filters, respectively, and 10 is a black matrix. Parts corresponding to those in FIG.

In FIG. 6, a front glass substrate 1 is provided with a color filter 9R having a characteristic of transmitting only R light opposite to an R cell provided with a phosphor layer 5R.
A color filter 9G having a characteristic of transmitting only G light is provided opposite to the G cell provided with the color filter 9B, and a color filter 9B having a characteristic of transmitting only B light is provided opposite to the B cell provided with the phosphor layer 5B. Is provided.

According to such a configuration, the R light emitted from the R cell
The light passes through the color filter 9R, the G light emitted from the G cell passes through the color filter 9G, and the B light emitted from the B cell passes through the color filter 9B.

In the R cell, G and B light is absorbed by the color filter 9R, and only the R light is incident on the external light incident from the front glass substrate 1 side. After being reflected by the phosphor layer 5R,
The light is emitted to the outside through the color filter 5R, the front glass substrate 1, and the like. In the G cell, the R and B lights are absorbed by the color filter 9G, and only the G light enters and is reflected by the phosphor layer 5G. Thereafter, the light is emitted to the outside through the color filter 5G, the front glass substrate 1, and the like. In the B cell, only the B light is incident upon absorption of the R and G light by the color filter 9B, and the phosphor layer 5B
Is emitted to the outside through the color filter 5B, the front glass substrate 1, and the like. Therefore, even if external light is incident from the front glass substrate 1, the amount of external light reflected from each cell is reduced, and the entire screen of the PDP is darkened and the contrast is improved.

In this conventional example, between the cells on the front glass substrate 1 side, ie, between the color filters 9R, 9G, 9B.
A black lattice made of a black light-absorbing material, that is, a black matrix 10 is provided therebetween, and the black matrix 10 absorbs incident external light. As a result, the amount of reflected external light emitted from the front glass substrate 1 to the outside is further reduced, and the contrast is further improved.

Another conventional method for improving the contrast is described in Japanese Patent Application Laid-Open No. 5-299022.

This will be described with reference to FIG. 5. A dark coloring material is mixed at the end of the partition wall 3 on the front glass substrate 1 side.
The light-absorbing property is given to the tip surface. this is,
A function equivalent to that of the above-described black matrix is provided. Part of the external light incident from the front glass substrate 1 is absorbed by the front end surface of the partition wall 3 and reflected by the phosphor layer of the cell to form a front surface. The contrast is improved by reducing the amount of external light emitted from the glass substrate 1.

[0017]

By the way, in the conventional example described in JP-A-59-36280, external light incident from the front glass substrate is absorbed by a color filter and a black matrix. Therefore, the amount of reflected external light emitted from the front glass substrate can be sufficiently reduced, and the contrast can be greatly improved.However, in order to sufficiently exhibit such an effect, The position of each color filter 9R, 9G, 9B needs to be matched with the position facing the R cell, G cell, B cell with high precision, and the position of the black matrix 10 is also located at the tip of the partition wall 3. It is necessary to match the position to the opposite position with high accuracy. However, the width of each cell and the color filters 9R, 9G, 9B, the width of the tip of the partition 3 and the width of the black matrix are very small, and the front surface on which the color filters 9R, 9G, 9B, the black matrix 10 and the like are formed. When a PDP is formed by combining the glass substrate 1 with the rear glass substrate 2 on which the partition walls 3 and the phosphor layers 5R, 5G, 5B are formed,
It is very difficult to match such small width dimensions with high accuracy.

On the other hand, Japanese Unexamined Patent Application Publication No.
In the conventional example described in Japanese Patent Application Laid-Open Publication No. H11-260, a dark-colored portion corresponding to the black matrix 10 is formed in advance on the partition walls 3, and the positional relationship between the dark-colored portion and the partition walls 3 is set in advance with high accuracy. When the PDP is formed by integrally combining the front glass substrate 1 and the rear glass substrate 2, it is not necessary to consider the positional relationship between the dark colored portion and the partition walls 3. Combination work with the substrate 2 becomes easy.

However, in this conventional example, since only the dark colored portion corresponding to the black matrix is formed, the effect of reducing external light incident from the front glass substrate 1 side is not sufficient, and the contrast is greatly increased. No improvement can be expected.

An object of the present invention is to solve such a problem.
It is an object of the present invention to provide a plasma display panel which has a structure which facilitates a work of assembling a front glass substrate and a rear substrate at the time of manufacturing, and which can greatly improve contrast.

Another object of the present invention is to provide a plasma display panel capable of obtaining high luminance.

[0022]

In order to achieve the above object, the present invention provides a color filter layer on a front glass substrate side in a cell, and a phosphor layer for emitting color light on the color filter layer. And a light reflection layer is provided on the rear substrate side in the cell.

According to this structure, the phosphor layer emits at least color light emitted on the front glass substrate side and color light emitted on the rear substrate side. The former is emitted directly to the outside through the front glass substrate. The latter is reflected by the light reflecting layer provided on the rear substrate side, and is emitted to the outside through the front glass substrate. External light that enters through the front glass substrate enters the cell, is reflected by the reflective layer, and is emitted to the outside through the front glass substrate. A part (color light other than the specific color light) is absorbed by the color filter. For this reason, the amount of reflected external light emitted from the front glass substrate to the outside is sufficiently reduced, and the contrast is greatly improved.

According to the present invention, the above-mentioned partition is formed on the above-mentioned front glass substrate.

With this configuration, the above-mentioned color filter can be formed on the front glass substrate side on which the partition walls are formed in the same manner as the phosphor layer, and the front glass substrate and the rear substrate are integrated. Before this, the positional relationship of the color filters with respect to each cell has already been set with high accuracy. Therefore, the front glass substrate and the rear substrate can be integrated without considering the positional relationship between the color filter and the cell.

In order to achieve the above and other objects, according to the present invention, the partition is made of a transparent material, and the address electrode provided on the front glass substrate is made of a transparent electrode and a metal bus electrode. The metal bus electrode is provided in a region facing the end surface of the partition wall on the front glass substrate side. Further, the present invention has a configuration in which an address electrode and a display electrode are provided on the back substrate side.

With this configuration, the color light emitted from the phosphor layer includes not only the color light emitted on the front glass substrate side and the back substrate side as described above, but also the color light emitted on the partition wall side. Such color light is emitted to the outside through transparent partition walls and a front glass substrate. The same applies to the color light reflected toward the partition wall by the light reflection layer on the rear substrate side. As a result, the amount of color light emitted from the front glass substrate to the outside increases, and the luminance increases. Further, a transparent electrode is used as an address electrode provided on the front glass substrate side, and a metal bus electrode integrated with the transparent electrode is disposed so as to face an end surface of the partition wall on the front glass substrate side. Also, the metal bus electrode can be made smaller (for example, the width dimension of the metal bus electrode is almost half the width dimension of the end face of the partition on the front glass substrate side), and the amount of color light passing through the partition is blocked by the metal bus electrode. Percentage is small. As a result, the amount of color light emitted from the front glass substrate to the outside is further increased, and the luminance is further increased. Further, by providing the address electrodes and the display electrodes on the rear substrate side, the amount of color light emitted to the outside through the front glass substrate is further increased, and the luminance is further increased.
